Hello and welcome!
It sounds like you are well on your way down a path that is interesting and meaningful to you. I wish you all the best.
To answer your question about worshiping the Lord and Lady:
Worship of a God and Goddess (or the Horned God and the Triple Goddess) is part of the Neo-Pagan religion to which Wicca is a part as well as religious Witchcraft. Think of Neo-Paganism as a big umbrella - under that umbrella are many of the other Earth-based religions, Wicca included.
In many of these Neo-Pagan religions, magic is practiced. It can be a religious or spiritual ritual expression as well as a practical way to get things done. Therefore magic and spellcraft both exist harmoniously in these traditions (as well as other magico-religious traditions such as Vodoun, Santeria, Candomble, Taoism, Hinduism, etc.).
Different countries, different cultures, different tribes, and different religions all have their own distinct magical traidtions. There are also plenty of magical traditions which are non-denominational. Also, most folk magic is within the religious context of the culture. For example American hoodoo is generally practiced by Christians, Baptists and other protestants.
Actually, most of the world's magic practitioners are not Neo-Pagan. Neo-Pagan magics are but a drop in the bucket compared to all the magic practiced around the globe. It is a common misconception that all modern magic is Wiccan or Witchcraft-type magic. This is not so, and actually, those types are actually in the minority. Wicca is just what sells books and what is promenient in popular culture.
So, to answer our question, this is a site devoted to magic. You will find people here of all faiths: Wiccan, Witches, Satanists, Christians, Neo-Pagans, Catholics, Atheists, Agnostics, and the like. What we all have in common is we practice magic, and you can browse around and see we're a very assorted lot.
Worship of the Lord and Lady is a Pagan religious practice. You will find many people who do worship the Divine in that form, but you will find just as many who don't. It's magic which is the common thread.
I hope this answers your question and isn't too confusing.
